After the 1990 to 1991 conflict in the Persian Gulf, many Gulf War Veterans began reporting numerous unexplained symptoms including, but not limited to, systemic pain, fatigue, flu-like symptoms, and difficulty with memory/concentration. These symptom clusters are now referred to as Gulf War Illness (GWI). Although the etiology of GWI is still debated, as many as 250,000 former service members have been continually suffering from GWI since 1991, making the need for treatment urgent. A broad variety of treatments have been considered for GWI, but there has not been a broad and comprehensive assessment of what is known and not known about GWI treatment. We conducted a systematic review to catalogue the types of treatments that have been examined for GWI, to evaluate the effectiveness and harms of these interventions, and to identify promising and ongoing areas of future GWI treatment research. ⋯ Cognitive behavioral therapy (moderate SOE), exercise (moderate SOE), and mindfulness-based interventions (low SOE) may be effective in improving several symptom domains in patients with GWI. Doxycycline was ineffective and associated with harms (moderate SOE). Larger, more rigorous studies are needed to confirm the benefits found in completed trials. A wide array of treatments are being assessed in ongoing trials. A sufficient evidence base will need to be developed to guide clinicians about which treatments are most likely to be effective in clinical practice and which treatments should be avoided.

Optimizing Fetal Aneuploidy Screening in an Austere Military Clinical Environment: A Prenatal Cost Comparison.
Austere clinical settings, including remote military installations, face unique challenges in screening pregnant women for aneuploidy. The objective of this study was to compare the direct and indirect prenatal costs of traditional 2-part serum-based screening to cell-free DNA (cfDNA) for detection of trisomies 18 and 21 for a military treatment facility with limited in-house perinatal resources. ⋯ Cell-free DNA as an initial screening strategy offers enhanced detection rates for trisomies 18 and 21 but remains more costly than traditional screening when incorporating direct and indirect expenses. In a low volume setting with limited resources, the added cost may be justified given the implications of unrecognized aneuploidy.

Dental Readiness Classifications (DRCs) enable the Military Health System to prioritize dental care in garrison, minimizing dental emergencies and mission degradation during deployments. Over half (52.4%) of 2008 military recruits presented with high-priority urgent needs classified as DRC3 upon initial dental examination and 18.1% required extensive treatment, needing 7 or more restorations, in order to achieve operational dental readiness. The purpose of this study is to identify risk indicators for urgent and extensive dental treatment needs in current U.S. Air Force (USAF) recruits so that Dental Corps leadership can target interventions to maximize oral health, prioritize resources, and reduce health expenditures in this patient population. ⋯ Among USAF recruits, oral health disparities are observed in certain groups. The study findings can inform targeted utilization of resources and interventions to efficiently optimize oral health and operational dental readiness and decrease dental expenditures. Additionally, a two-question screening tool is proposed to facilitate priority assignment for dental examination during boot camp. This tool has the potential to correctly identify nearly 90% of those with urgent and extensive dental treatment needs at half the typical workload.

Increases in C-reactive protein (CRP) are used to track the inflammatory process of COVID-19 and are associated with disease state progression. Decreases in heart rate variability (HRV) correlate with worsening of disease states. This observational study tracks changes in HRV relative to changes in CRP in COVID-19 patients. ⋯ Substantial decreases in HRV preceded elevations in CRP in the ensuing 72 hours with a 90.9% positive predictive value. Early detection of increasing inflammation may prove vital in mitigating the deleterious effects of an abnormal inflammatory response, particularly in COVID-19 patients. This capability could have a major impact in triage and care of moderate to severe COVID-19 patients in major medical centers as well as field hospitals. This study demonstrates the potential value of short-segment, intermittent HRV analysis in COVID-19 patients.

Sleep disturbance is prevalent among service members; however, little is known about factors that compromise sleep in unique operational environments, such as naval ships. Given the importance of sleep to health and performance, it is critical to identify both causes and potential solutions to this serious issue. The objective of this qualitative study was to elucidate the barriers to sleep and the strategies service members use to improve their sleep and combat fatigue while living and working aboard ships (i.e., underway). ⋯ Service members reported many unique barriers to sleep in the shipboard environment, yet many did not report the use of strategies to mitigate them. Further, few used alerting techniques when fatigued. This at-risk population could benefit from targeted educational interventions on sleep-promoting behaviors, prioritization of sleep, and fatigue mitigation.
